My scheduled new & changed scan ran a little slower than normal this
morning, but it did not see all the files as changed. Looks like this is
fixed and a full scan following a time change is no longer necessary on
Windows. :)

Haven't tested the "fall back" situation, but so long as you're
adjusting the timestamps by the opposite amount when it occurs, I would
call it fixed.

Re: [slim] Windows Users: Run a full library scan following time changes

2016-03-15 Thread Michael Herger

So, you're able to reliably detect that a DST time change has occurred
since the last scan?


LMS does set a flag in the database whether DST is on or off. Before 
running the scan it checks that flag against the current DST state and 
updates the timestamps column if needed (on Windows only).

Re: [slim] Windows Users: Run a full library scan following time changes

2016-03-15 Thread Michael Herger

It looks like a New & Changed scan did NOT see any music files as
changed following the time change. But, it did see all of the covers as
having changed and resized and re-cached all of them.


Are you using all standalone artwork (eg. cover.jpg) or mostly embedded? 
I looked into this, and I guess if I looked into it before, I probably 
came to the same conclusion as I've come today: things are complicated 
:-). It only applies to cases where you're using an external artwork 
file, was its timestamp would be reported incorrectly too. Unfortunately 
the artwork cache isn't a nice table where the timestamp is its own 
column. Therefore we can't just bump that timestamp as we do for the 
tracks. Which means we can't easily fix this. Not easily enough to make 
it worth the hassle and risk imho. After all that stage doesn't have the 
same negative impact as does a full rescan of the tracks table.

This coming Saturday night. I'm not sure I ever really tested the fix,
but I've disabled my nightly auto-rescan, so I'll be able to know for

Re: [slim] Windows Users: Run a full library scan following time changes

2015-04-04 Thread Michael Herger

That's great news. Michael, what was the workaround?


That would indeed be great news.

How it works? After every scan I'm setting a flag whether the scan 
happened in DST or not. And before every new  changed scan it would 
check that flag against the current DST state. If it changed, then it 
runs an update on the tracks table to modify it according to the change 
and sets the flag to the new status. (and all of this in Windows only)


I decided to do this one time update rather than add more logic to all 
of the scanner code spread across multiple source files. Seems to be 
good enough. Keep fingers crossed. There will be a next DST change in 
the opposite sense :-).

Re: [slim] Windows Users: Run a full library scan following time changes

2015-03-06 Thread reinholdk

You're certainly right, still three weeks to go for me.

Just wondered if there's a command line argument for LMS to start a full
scan, so that one could create a scheduled task.
But a command line arg is not needed. This should do the trick: create a
batch file to stop the LMS service (net stop Logitech Media Server),
delete the db files and then restart the service (net start Logitech
Media Server). Then create a scheduled task that runs under an admin
account triggered after the two DST switching times of the year...

Re: [slim] Windows Users: Run a full library scan following time changes

2013-11-04 Thread JJZolx

If the new  change scan rescanned every file in the library, then it
shouldn't rescan those files again, because the new timestamps would be
recorded in the library database. One the other hand, if there's some
bug is causing only 1/2 of the files to be scanned each time, then it
would keep doing it until it finishes the whole library.

I recall a couple of similar bugs where only half of the tracks expected
to be scanned actually do get scanned. Don't know if they're related.

http://bugs.slimdevices.com/show_bug.cgi?id=17438

IMO, it's good to run a full rescan periodically anyway.

Re: [slim] Windows Users: Run a full library scan following time changes

2013-11-03 Thread JJZolx

Bump. A reminder for anyone running LMS under Windows:

Run a full clear library  rescan everything following a time change
to or from Daylight Savings Time. Otherwise, the next new  changed scan
may rescan the whole library, which is typically much slower than doing
a full scan.

Been there, done that. :)

Any ideas why new and changed scans following the DST switch always find
half the number of modified tracks compared to the previous scan?

Actually, the UK and western Europe (at least) changed to standard time

Thanks for the heads-up.

I could not for the life of me figure out what was going on with the
new and changed scan rescanning the whole library.

Re: [slim] Windows Users: Run a full library scan following time changes

2012-03-11 Thread JJZolx

Reminder to those running the server under Windows:

You should run a full clear  rescan everything today. Before you run
your next new  changed scan, or else you'll probably see that new 
changed scan rescan every file in the library due to the time change.
Which is a lot slower than just running a full rescan.

And I might add (from hard experience), if you don't run a complete
rescan, LMS keeps running a prolonged version of the new  changed scan
each time it runs thereafter.

This thread didn't exist this AM when I first experienced the problem.

LMS has succeeded in wasting another hour or so of my already shortened
weekend :(

Yes, they said that IF it happened, then there'd be 6 years' notice.  

Time enough, you would think, 6 years.  But Time does not seem to be
what we think it is.  It does (or doesn't) match the Earth's rotation. 
It gets delayed by some old guys in Paris who decide whether to add a
second now and then.  It gets shifted around, so that midday - in our
neck of the woods - occurs at a quarter past one for half the year; our
sundial is never right.

Beats me how anything works, really.

Anyway, that decision was postponed until 2015:

Is UTC time stored, or local time ?

Window's isn't changing the time of the files - a given application
(like explorer) gets timezone adjusted dates based upon the user's
timezone settings.

No, Windows isn't modifying the times of files.  In NTFS file systems
UTC is stored.  But what happens is that the timezone offset is changed
when DST begins and ends.

Here's an article that explains the problem, and even the reasons why
Microsoft chose to implement it as they have.

http://www.codeproject.com/KB/datetime/dstbugs.aspx

I'm not sure if SqueezeCenter could work around the issue.  I think it
would depend upon whether ActiveState Perl can return pure UTC file
times and then SC store those instead of local times.

Yes.

The NtfsDisableLastAccessUpdate setting is supposed to be a performance
tweak, correct?

http://www.microsoft.com/technet/prodtechnol/windows2000serv/reskit/regentry/46656.mspx?mfr=true

This only disables updating of last-access times (and I think it only
applies to directories, not files).  SqueezeCenter stores file
last-modified timestamps in its database, not last-access.

Yes, that is what is claimed but I have not seen any quantifiable data

Good to know...thanks for the info as I noticed that my usual re-scan
took about 45 minutes longer than expected the night of the
time-change.

If you were running a new and changed scan then it probably ended up
rescanning every file in the library.

Yes, I add music regularly by using the My Music\folder\album
method.
After that I initiate a scan for MIP integration.
I noticed that when I executed a backup next day, all my previous music
files reported date  time change.
Subsequently, I may have accidentally avoided the slowdown you
mention.
What luck!
